As someone who has a lifelong interest in Einsteinian Physics, Psychology, and the development of concepts aross time, reading this text is exciting to me because it combines them all together in one volume. This table of contents might explain better:
PRINCIPLES OF TOPOLOGICAL PSYCHOLOGY BY KURT LEWIN Professor of Child Psychology, Iowa Child-Welfare Research Station, University of Iowa
PART I. THE TASK OF PSYCHOLOGY AND THE FOUNDATIONS OF TOPOLOGICAL AND VECTOR PSYCHOLOGY
I. THE PRESENT STATE OF PSYCHOLOGY
II. FORMULATION or LAW AND REPRESENTATION OF SITUATION Law and individual case The constructive representation of the situation Person and environment; the life space Ways in which the life space is represented.
III. GENERAL CONSIDERATIONS ABOUT REPRESENTING LIFE SPACE The life space as the totality of possible events Inventories and systems of behavior Constructive procedure: Summary Good and poor abstraction; the method of approximation.
IV. CONTENT AND EXTENT OF THE PSYCHOLOGICAL LIFE SPACE Appearance and reality in psychology Experience and psychological existence What is real is what has effects Phenomenal facts and physics Life situation and momentary situation Quasi-physical, quasi-social, and quasi-conceptual facts within the life space The quasi-physical facts The quasi-social facts The quasi-conceptual facts Influences by way of perception and "gross somatic" influences.
V. CAUSAL INTERCONNECTIONS IN PSYCHOLOGY The historical and the systematic concept of causality Existence, temporal and causal relationships The principle of "concreteness" The relational character of causal facts The principle of "contemporaneity" Past and future; the unreal and the indeterminate in the life space Existence and temporal determination of a psychological fact and its content Content as a property The indeterminate.
VI. THE PSYCHOLOGICAL LIFE SPACE AS SPACE IN THE SENSE OF MATHEMATICS Examples of space-like relationships in the life space Space of free movement; locomotion, forces Regions within the person; The mathematical concept of space Topological space Metrical space The application of the concept of space and physicalism.
VII. PSYCHOLOGICAL SPACE AND PSYCHOLOGICAL DYNAMICS Problems of pure mathematics and problems of coordination The instability of psychological situations Necessary conditions for the application of metrical and topological concepts to the life space Space and dynamics. The history of the concept of space in physics and psychology The fundamental concepts of dynamics.
VIII. THE PSYCHOLOGICAL WORLDS AND THE PHYSICAL WORLD Physical and psychological space The singleness of the physical world and the plurality of the psychological worlds The physical world as a dynamically closed unity and the psychological worlds as dynamically unclosed unities.
IX. MATHEMATICAL REPRESENTATION AND PSYCHOLOGICAL THEORY Concept, picture, and symbol Concept and model Physiological theories of psychological processes Representation and explanation.
PART II. TOPOLOGICAL PSYCHOLOGY A. CONCEPTS or TOPOLOGY WHICH ARE FUNDAMENTAL FOR PSYCHOLOGY X. CONCEPTS OF TOPOLOGY FUNDAMENTAL FOR PSYCHOLOGY The concept of region. The connected region Closed and open regions Limited and unlimited regions Simply and multiply connected regions Jordan curve, boundary, path Foreign regions.
B. TOPOLOGY OF THE PSYCHOLOGICAL ENVIRONMENT XI. PSYCHOLOGICAL REGIONS, LOCOMOTIONS, AND COMMUNICATIONS Coordinating definitions The psychological region Psychological locomotion Being inside or outside of a region The inner structure of a psychological region Determination of the connectedness of regions Nonconnected regions Multiply connected regions Limited and closed regions Representation as path or as more than one-dimensional region Representation as point or as more than one-dimensional region Locomotions of a surrounding field Thing and medium.
XII. BOUNDARIES OF PSYCHOLOGICAL REGIONS Definition and determination of psychological boundaries - Sharpness of a boundary; boundary zones Dynamic properties of psychological boundaries Barriers Boundaries which affect communication Boundary zones which can be passed only with difficulty Zones of undetermined quality.
XIII. THE RELATIVE POSITION OF Two REGIONS Foreign regions Overlapping regions; the relative weight of situations Difficulties in representing the relative position of two regions The two principal possibilities for the representation of the inaccessibility of a point Topological and dynamical aspects of the representation of limitations Discrete paths and their totality Homogeneous and differentiated barriers; approach and withdrawal Barriers and adits.
XIV. STRUCTURAL CHANGES Differentiation, integration, and restructuring Changes of structure and locomotion Changes of magnitude and of distance Dynamic conditions of structural changes; fluidity, elasticity, plasticity.
XV. THE LIFE SPACE AS FINITELY STRUCTURED SPACE C. TOPOLOGY OF THE PERSON
XVI. THE PERSON AS A DIFFERENTIATED REGION IN THE LIFE SPACE
XVII. FUNDAMENTAL CONCEPTS AND COORDINATING DEFINITIONS FOR THE REPRESENTATION OF THE PERSON Coordinating definitions for environment and for person Dynamic dependency Boundaries and boundary zones Remarks about strong and weak gestalten; Gestalten with different degrees of dynamic unity Dynamic properties of personal regions Tension Groups of tension systems Structure of the person Inner-personal regions and the motor-perceptual region; Central and peripheral inner-personal strata Individual differ- ences in the structure of the person The degree of differentiation of the person The kind of structure and the function of the part regions The connection between dynamic and topological factors.
D. DIMENSIONS OF THE LIFE SPACE
XVIII. THE DIMENSIONS OF THE LIFE SPACE Mathematics of dimensions The dimensions of the psychological environment Reality Degrees of irreality Problems of dimensions of the person The differentiation of the life space in the dimension reality-irreality.
